I am looking for the "Create Pose Asset" button in the "Animation" side tab (as seen below in version 3.4.0).
As far as I was aware, this button was the "intended" way to create pose assets to be used on armatures. In fact, the user manual directly refers to this button:
For preset assets, there will be a dedicated button for the different asset types. Currently poses are the only preset assets; use the Create Pose Asset button in the Action editor.
However, since updating to version 3.5.0, this button is now gone (as seen below).
Instead, the "Create Pose Asset" option now appears to be located in the "Asset" dropdown menu of the Asset Browser, which is a bit more tedious to access (which accumulates to a substantial time loss over time when animating). This seems like a strange thing to remove, as it slows down the process of quickly saving poses for later use, so I would love to know whether this button is still accessible somewhere besides the Asset Browser's dropdown menu. Thank you!
